In a Triangle PQR if ∠Q = 3 ∠R = 2 (∠P +∠R) then value of ∠Q will be 1. 110° 2. 120° 3. 40° 4. 102°

Answer»

Correct option is 2. 120°

Q = 3R = 2(P + R)

Q = 2P + 2R

3R = 2P + 2R

R = 2P

∴ Q = 2P + 4P = 6P

∴ P + 6P + 2P = 180° ⇒ 9p = 180° ⇒ p = 20°

∴ Q = 6 × 20 = 120°

Answer» Correct option: (2) 3 (x – y) (y – z) (z – x) Explanation: Let a = x - y b = y - z c = z - x a + b + c = x - y + y - z + z - x = 0 ∴ a³ + b³ + c³ = 3abc (x - y)³ + (y - z)³ + (z - x)³ = 3(x - y) (y - z) (z - x)

944.

Value (x – y)3 + (y – z)3 + (z – x)3 is(1) (x – y)3 (y – z)3 (z – x)3 (2) 3 (x – y) (y – z) (z – x)(3) x3 + y3 + z3 – 3xyz (4) x3 + y3 + z3 – 2x2y – 2y2z – 2z2x.

Answer»

Correct option: (2) 3 (x – y) (y – z) (z – x)

Explanation:

Let a = x - y

b = y - z

c = z - x

a + b + c = x - y + y - z + z - x = 0

∴ a³ + b³ + c³ = 3abc

(x - y)³ + (y - z)³ + (z - x)³ = 3(x - y) (y - z) (z - x)
